When navigating the as-yet-unknown films of a festival program, nationality still provides a persuasive point of reference for some, a feeling underlined by the proud declarations issued by national funding organizations, promotional bodies, or particularly partisan members of the press once titles have been announced. This year’s reduced Berlinale Forum lineup also invites tenuous lines of this kind to be drawn (two films from Argentina, two films from Canada!), although the three Franco-German co-productions shot elsewhere say far more about how films are made in 2021.
